Lab Streaming Layer

Qualisys Lab Streaming Layer App

Stream Qualisys Track Manager (QTM) 3D and 6DOF data as Lab Streaming Layer (LSL) Motion Capture (MoCap) data.

Dependencies

• Python 3.5 or above
• Python tkinter (GUI, see google)
• Qualisys SDK for Python
• Python interface to LSL pylsl

Installation

1. Upgrade to latest pip

python -m pip install pip --upgrade

2. Install dependencies

python -m pip install -r requirements.txt

If this is unsuccessful, consult the links in the dependencies section for instructions on how to manually install them. Also note that some Python installations include tkinter by default and some require you to install it separately.

3. (Optional) Install dev dependencies to be able to run the tests

python -m pip install -r requirements-dev.txt

Usage

1. Ensure QTM is running either locally or on an external host that you are able to ping
2. Start LSL App

python -m qlsl.gui

3. Enter address, port, and start

Once started and connected, the app is either in a Waiting or Streaming state. In the Waiting state there is no LSL stream outlet open, as the app is waiting for QTM to start streaming. When QTM is streaming, the app is in the Streaming state and QTM data is passed through an LSL stream outlet. The app toggles between these states as QTM starts/stops streaming.
